Description

  The present invention relates to an artificial pond device that is constructed in an outdoor garden or the like, and more particularly to an artificial pond device that circulates purified water by circulating water in the pond.

  Ornamental ponds may be built in outdoor gardens. These ponds are used as part of the garden landscape for raising corals and goldfish, and for growing lotus and other plants. In reservoirs where water does not flow, such as ponds, the stored water will stagnate, so remove the debris from the surface of the pond during circulation to clean the stored water. A device may be attached to do this. For example, in a reservoir that circulates and uses water, a water purification method that purifies water by passing water through earth and sand laid on a part of the reservoir and a sand layer provided at the bottom of the reservoir Has been proposed (see Patent Document 1).

  In addition, there is a method of using clay at the bottom of the pond so that the volume of water stored in the pond is stabilized, but maintenance and cost are required. Therefore, the bottom of the pond may be made of concrete to reduce the maintenance cost, but there were problems such as high initial costs. In addition, although the number of reservoirs that can be built at low cost by burying a plastic gourd-shaped pond shape has increased, it has become impossible to freely select the shape of the reservoir. Furthermore, the stored water transpirations in large quantities regardless of the season, the water level drops significantly, and replenishment of tap water requires a large amount of cost, so it was necessary to reduce the transpiration of water.

It is a whole perspective view showing a partial section of an artificial pond device concerning one example of the present invention. It is a top view of the 1st container of a 1st embodiment which shows a level difference part neighborhood.

  The artificial pond device 10 of the present invention includes a pond part 11 exposed to the outside and a water storage part 20 disposed adjacent to the pond part 11. As described in claim 2, the pond part 11 and the water storage part 20 are formed by the waterproof sheet 70, so that the water stored in the artificial pond device 10 is not absorbed into the ground and the water level is unlikely to drop. By using a waterproof sheet-like material, the shape and size of the pond portion 11 and the water storage portion 20 are not limited and can be formed in any shape.

  As the waterproof sheet, a conventionally known sheet is used, and for example, a sheet obtained by molding ethylene / propylene / diene rubber (EPDM), polyvinyl chloride (PVC), or the like into a sheet shape. If a stretchable material is used, it can be easily adapted to the shape of the bottom of the pond portion 11, etc., so in this example, ethylene / propylene / diene rubber (EPDM) is adopted in view of weather resistance and deterioration resistance. did.

  After shaping the pond part 11 into an arbitrary shape, the pond part 11 and the water storage part 20 are formed by laying a waterproof sheet 70 so that the stored water is not absorbed into the ground. Since the stored water is not absorbed into the ground and the water volume is unlikely to decrease, the stored water can be circulated stably. Furthermore, by forming the rainwater channel 90 for introducing rainwater into the pond part 11, the water level can be stably maintained even when the water volume is reduced in summer when the amount of water evaporation is large. The rainwater channel 90 may be connected to a rain gutter of a house to increase the amount of rainwater flowing in. As a result, water can be replenished to maintain the stability of the water volume, the water temperature, and the water quality. Furthermore, it is also possible to form a discharge path 91 that discharges water that overflows when the amount of water flowing in increases and exceeds the amount of water stored in the water storage unit 20. Since a stable amount of water can be maintained, the stored water can also be used for emergency emergency water.

  The water surface position of the pond part 11 is set to be higher than the upper surface of the water storage part 20, and water flows from the pond part 11 into the water storage part 20 through the step part 21. Since the water moves greatly when flowing in through the stepped portion 21, the area where the water comes into contact with the air is increased, and it is possible to improve the water quality. If the height of the step is about 5 to 10 cm, the water noise during inflow can be reduced. Also, if you make a large step, you can create a waterfall-like landscape. In the embodiment of FIG. 1, a partition portion 80 is formed between the pond portion 11 and the water storage portion 20 in order to form the step portion 21. The upper part of the partition part 80 is exposed to form the step part 21, and the pond part 11 and the water storage part 20 are formed separately.

  As shown in FIG. 2, the water in the pond part 11 flows into the water storage part 20 beyond the step part 21, so that dust such as fallen leaves floating on the water surface accumulates between the step part 21 and the upper part of the water storage part 20. Therefore, it is possible to prevent the water in the pond part 11 from becoming difficult to flow into the water storage part 20 and to maintain a smooth circulation. The upper exposed portion of the partitioning portion 80 can be decorated with a stone plate or the like and harmonized with the surroundings to improve the beauty. The pond part 11 and the water storage part 20 can also be partitioned by a water channel excavated from the ground, a skimmer, a tunnel-like product, or the like.

  A filtration unit 30 is formed in the upper part of the water storage unit 20, and water that has flowed in through the stepped part 21 passes through the filtration unit 30 and is stored in the water storage unit 20. As shown in FIG. 2, the filtering unit 30 can collect and collect dust such as fallen leaves L floating on the water surface, which facilitates collection of the dust. Furthermore, the landscape can be improved by laying gravel G or the like. A lattice-like box can be used for the filtration unit 30. By using a filter having a high strength, it is possible to apply decoration not only to light gravel but also to the landscape. In addition, by laying a water-permeable sheet such as non-woven fabric 31 on the upper part of the filtration unit 30, fine gravel and sand can be laid, and further improvement in aesthetics can be desired. Can be taken.

  The water storage unit 20 is disposed adjacent to the pond unit 11 due to the structure into which the water flows, and is buried underground. Thereby, since the water stored in the water storage part 20 is not exposed outside, sunlight is not directly irradiated, but a rise in water temperature can be prevented. Since the water temperature of the water storage unit 20 is difficult to rise, it is possible to prevent an increase in the water temperature of the entire water circulating in the artificial pond device 10, and to suppress the transpiration of water due to the water temperature rise, and to suppress the growth of algae, thereby preventing the artificial pond The device 10 can be made difficult to get dirty.

  Below the filtration unit 30, a water supply unit 40 provided with a water supply pump 41 and a water supply member 42 to the pond unit 11 is provided. The water supply unit 40 is provided in the water storage unit 20. In the embodiment, the water supply unit 40 is formed separately from the water storage unit 20 as described in claim 3. In the water storage unit 20, by separating the water supply unit 40, the water supply pump 41 can be easily taken out, and therefore, the water supply pump 41 can be easily cleaned.

  The water supply pump 41 is disposed in the water stored in the water supply unit 40, and circulates the water in the artificial pond device 10 by sending the water in the water supply unit 40 to the pond unit 11 through the water supply member 42. The water supply member 42 uses a porous tube 43, and in this embodiment, a member provided with a hole 44 is used. The hole 44 is adjusted to an appropriate size such that mud, dust and the like are not easily clogged. Moreover, in order to eliminate the clogging of the hole 44 of the porous tube 43 and the like, it is possible to eliminate the clogging or the like by supplying water with a strong pressure from the water supply pump 41.

  In addition, when the perforated pipe 43 is embedded in the bottom of the pond part 11 with gravel or the like, dust or the like deposited on the bottom can be lifted and collected by the step part 21 and the filtering part 30. The organic matter contained in the water fed from the holes 44 is decomposed by the oxygen that has been propagated on gravel, etc., and activated by the fed oxygen and the constant water temperature, and aquatic plants are planted to absorb nutrients and stabilize the water quality. be able to. Furthermore, the flow of water can be increased by increasing the amount of water transported, and can be carried and filtered to the stepped portion 30 before debris such as fallen leaves on the water surface settles. Since water can be fed from the entire bottom of the pond portion 11 by the perforated pipe 43, the amount of water passing through the gravel increases, and the water quality can be further stabilized.

  This artificial pond device 10 has a pond part 11 and a water storage part 20 provided with a filtration part 30 and a water supply part 40 provided at the lower part of the filtration part 30 adjacent to each other, and the water of the pond part 11 has a step part 21. Then, the water is stored in the water storage unit 20, and water is sent to the pond unit 11 by the water supply unit 40, and the stored water circulates. Therefore, it is possible to circulate water with a simple configuration and remove dust such as fallen leaves by filtration. Moreover, since the pond part 11 and the water storage part 20 are formed of the waterproof sheet 70, the stored water is not absorbed into the ground, so that it is difficult to reduce the water level. Since the water storage part 20 is buried underground, it is possible to keep the water level constant by suppressing an increase in the temperature of the stored water and suppressing the transpiration amount of the water.

Note that the artificial pond device of the present invention is not limited to the above-described embodiment, and may be configured to make it easy to float dust collected on the bottom of the pond by using a plurality of water supply members. Within a range that does not depart from the spirit, a part of the configuration can be changed as appropriate.
